* sftp: support for external SSH command and host verfication improvements - removed custom parsing of hostnames and verification and replaced with standard 'knownhosts' implementation. - added option to launch external SSH command which supports aliases, agent, etc. NOTE, we're still not supporting any cases where password needs to be entered on the command line, since that would be incompatible with the UI which uses client-server model. Fixes #500 Fixes #414 * site: updated SFTP repository connection instructions Fixes #590
